A patient is admitted to the cardiac care unit with an acute anterior myocardial infarction.The nurse assesses the patient to be diaphoretic and tachypneic,with bilateral crackles throughout both lung fields.Following insertion of a pulmonary artery catheter by the physician,which hemodynamic values is the nurse most likely to assess?
A) High pulmonary artery diastolic pressure and low cardiac output
B) Low pulmonary artery occlusive pressure and low cardiac output
C) Low systemic vascular resistance and high cardiac output
D) Normal cardiac output and low systemic vascular resistance

Question

In cardiogenic shock,cardiac output and cardiac index decrease.Right atrial pressure,pulmonary artery pressures,and pulmonary artery occlusion pressure increase and volume backs up into the pulmonary circulation and the right side of the heart.Pulmonary artery occlusion pressure increases in cardiogenic shock.Systemic vascular resistance is high and cardiac output is low in cardiogenic shock.Cardiac output is low and systemic vascular resistance is high in cardiogenic shock.
